Tree Removal Without Roots - Knowledgebase Question

Unfortunately, we had an old oak tree removed due to damage to the foundation of our home. The stump was grinded down apx. 8 inches but were concerned that the roots will continue to grow unless we remove? We heard you can cut out some roots or drill holes in remaining stump and pour a solution to kill the roots. Any advice would be helpful.
Thank you.

In my experience, an oak tree that has been cut down will die and the roots will cease to grow. The roots in the soil will eventually rot away naturally. (This is not true for all kinds of trees, as some other kinds will try to resprout from the stump.)
